Magstar is the only high performance marine wire set that practically eliminates radio interference with onboard electronics. Stainless steel spark plug terminals provide a positive corrosion-proof connection. Pure silicone boots provide maximum heat protection. Guaranteed for as long as you own your boat.

ferrules that engage in the distributor cap should have some spring retention force....these wires actually fell out of the cap when underway. tried to increase tension, still fell out. ended up glueing these wires into my new distributor cap. I ordered three set of these. will return the two unopend sets and would like to send back the installed set. I would get would talk to your supplier, perhaps they forgot to heat treat the parts.
